libsmb/clientgen.c: Fixed signed/unsigned compile warnings spotted by Herb.

param/loadparm.c:
smbd/oplock.c: Allow kernel oplocks to be turned off in the smb.conf file.
smbd/server.c: Move init_structs() to after the smb.conf file is loaded - preparation
               for making a "max open files" parameter.
